AssumingI that the parts of the` abovef'described apparatus areassembled `and adjusted to subnstantially thposition shown, and that`the belt llil' is being `drivenin `the `direction* indicated by thearrows on Fig.` 4, and that thinwalled articles areiheld on forms I inunrolled, lslightly. dis- I tended'condition, the operation of theapparatus is substantially asfollows:` As each formV I care I rying anarticle A moves sidewise past Ibelt (I8,

fthe upwardly moving `reach of thebelt engages "the'strengthening ring'B on the open Iend `ofara` `ticle `A androlls the article on Aitself andltoward the free end ofthe form andnnally removes the article from theformand impelsit into` the open `mouth of chute 5.' The belt is `drivenat such speed, in `relation tothe speed of the form, that y the articleis rolled upon" itself to a place so closely adjacent to its closed endthat the friction be? A L ,www

Whatis claimed is:

It will be noted that the longitudinal axis of each form I is inclinedat a small angle to the plane of belt I8 so that the ring B on thearticlel belt I8. By reason of this angularity ofthe form and belt, theform may pass rapidly over the relatively narrow belt and yet thearticle may be rolled for the full length of the form during` thatl Y.

brief interval of time.r l

As the angularity of the belt 'I8' tothe form `I is increased the speedof travel of the belt Amay.

be decreased,l for the article .on the form will be in contact with thenarrow belt. for a longer time due to that increased angularity.ASimilarly,

when the angularity is decreased the speed of the belt should beincreased. Similar-ly, when vthe speed of travel of the forms is variedthe anguslarityor speed of the belt, or both, may be varied all to theend that articles may besatisfactorily removed from the forms. y Forexample, at a certain speed'of travel ofthe forms-the angularity of thebelt may be small and the speed ofthe belt may be low. 'For a' greaterspeed of travel of the forms the angularity orY the speed of the beltmay. be increased. For; stilll higher speeds v of travel of the formsboth theangularity and speed of the belt may be increased, I I

Preferably, the belt I8 isl molded in a circle. When so molded it has'atendency to bow outwardlybetvveen thepulleys I2 and engage-the articleon the formxbetween the supporting pulleys. This tendency isof/advantagewiththe .progressively increasingthickness of ring for thebelt initially tends to press against the smalldiameter ring at the openend of the article and this pressure tends to increase as the article`is rolled'upon itself andthe ring increases in thickness. Thistendencyofthe belt to resume its circular molded shame-makes it Iunnecessary toIprovide an abutment on the inside surface of the vbelty underusualoperating conditions,` altho the vWhile the above describedapparatushasbeen foundpto kbe commercially valuable in connection andcompositions `from their forms-.3j
